Detachable pet rope, intelligent pet rope and remote pet monitoring system

Abstract

The invention discloses a detachable pet rope, an intelligent pet rope and a remote pet monitoring system. The detachable pet rope comprises a buckle base and a detachable lock catch. The buckle base is provided with a base groove with an opening, and a rear wall clamping groove is formed in the rear groove wall of the buckle base; the detachable lock catch is provided with a groove insertion block inserted into the groove of the base, and the lower portion of the rear end of the insertion block is provided with a clamping hook part matched with the clamping groove of the rear wall. In the buckling process, an interval space is formed between the rear groove wall of the base and the groove inserting block, and the width size of the interval space is smaller than the protruding size of the clamping hook part. By means of the structure, when the clamping hook part is pulled towards the front groove wall of the base, the clamping hook part cannot be disengaged, and mistaken unlocking is prevented; when unlocking pulling force in a specific direction is applied to the front end of the lock catch, the interval space provides lifting and transverse moving space for the clamping hook part to retreat from the rear wall clamping groove, and smooth unlocking is achieved. Reliable locking and directional unlocking are achieved through a rigid structure, and the fatigue problem of an elastic element is avoided.

Description

Technical Field

[0001] This invention relates to pet products, and more particularly to a detachable pet leash, a smart pet leash, and a remote pet monitoring system. Background Technology

[0002] With social development and improved living standards, pets (such as dogs) have become important members of many families. In public places such as elevators, parks, and streets, using pet leashes to restrain pets and others has become a common consensus and a necessary measure to ensure the safety of pets and others.

[0003] A typical pet leash usually consists of two main parts: one is the pet harness or collar (collectively referred to as the wearer), which the pet needs to wear; the other is the leash, which is connected to the wearer at one end and is a grip end for the user to hold and lead the pet.

[0004] Some manufacturers have introduced buckle assemblies at the connection between the traction cord and the wearable part to enable quick connection and separation. Currently, the most widely used type on the market is a plastic snap-on buckle (also known as a side-press snap-on buckle or side-opening buckle). The male buckle has elastic latches (or snaps, elastic arms) on both sides. When the female buckle is inserted, the latches on both sides are compressed and retract, then elastically return to their original position and lock into the slot. To unlock, the release part of the latches must be pressed to disengage them from the slot.

[0005] However, these widely used plastic buckles have inherent technical flaws. Their locking and unlocking functions rely heavily on the elasticity of the latch, which, under frequent insertion and removal operations, is subjected to cyclic stress over a long period, making it prone to metal fatigue (if a metal spring is present) or plastic deformation (if the elasticity is inherent in the plastic itself), leading to weakened elasticity or even breakage. More importantly, plastic materials are prone to aging, embrittlement, and decreased strength after prolonged exposure to sunlight, temperature differences, and humidity outdoors, further accelerating the failure of the buckle. Once the locking function of the buckle fails, it will directly lead to pets accidentally getting out of control in public places, causing serious safety hazards such as getting lost, frightening others, or traffic accidents.

[0006] Therefore, given the problems of easy damage, easy aging, and insufficient safety of the plastic buckles commonly used in existing pet leashes, there is an urgent need for a more durable and reliable connection solution.

[0007] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0008] One objective of this invention is to provide a detachable pet leash, a smart pet leash, and a remote pet monitoring system that can solve the problem that the elastic buckles used in existing pet leashes are prone to failure due to fatigue and aging.

[0009] To achieve the above objectives, on the one hand, the present invention provides a detachable pet leash, including a wearable part for an animal to wear, a leash for a person to hold, and a rigid buckle for connecting the wearable part and the leash;

[0010] The rigid fastener includes:

[0011] The fastener base has an open base groove, the base groove has a front base groove wall and a rear base groove wall that are arranged opposite to each other, wherein the rear base groove wall has a rear wall slot.

[0012] The detachable latch has a recessed insert that is inserted into the recess of the base through the opening of the recess of the base. The lower part of the rear end face of the recessed insert near the rear wall slot has a hook that protrudes toward the rear wall slot.

[0013] in,

[0014] When the detachable latch and the buckle base are engaged, the hook portion is accommodated in the rear wall slot, and there is a gap between the rear slot wall of the base and the recessed block;

[0015] The space is used to provide clearance for the hook to fully exit the rear wall slot when the front end of the detachable latch is lifted upward by an unlocking pull parallel to the opening orientation of the base groove;

[0016] Furthermore, the width of the interval space is smaller than the protrusion of the hook portion, so as to prevent the hook portion from completely exiting the rear wall slot when the detachable latch is subjected to a pulling force toward the front groove wall of the base.

[0017] Optionally, the recessed insert is provided with a magnetic insert component inside, and the bottom of the base recess is provided with a base magnetic insert component for magnetically connecting with the magnetic insert component;

[0018] The base magnetic suction component is located directly below the opening of the base groove and biased towards the side of the rear wall slot. It is used to apply a magnetic force towards the rear and downward to the insertion block magnetic suction component during the fastening process, so that the upper part of the rear end face of the groove insertion block close to the upper edge of the rear wall slot is tightly attached to the upper edge of the rear wall slot, so as to maintain the fastening state of the detachable lock and the fastener base.

[0019] Optionally, the front groove wall of the base is an inclined surface, and the width dimension from the front groove wall of the base to the rear groove wall of the base gradually decreases from top to bottom.

[0020] Optionally, the detachable latch also includes a latch body disposed above the recessed insert, the latch body extending rearward to form a rear protrusion for connecting the traction rope;

[0021] The latch body protrudes forward to form a forward protrusion for connecting the unlocking pull cord.

[0022] Optionally, the upper part of the front end face of the recessed insert near the front groove wall of the base is provided with a front protrusion protruding towards the front groove wall of the base, so that the gap between the upper part of the front end face and the front groove wall of the base is smaller than the gap between the lower part of the front end face and the front groove wall of the base.

[0023] On the other hand, a smart pet leash is provided, including the aforementioned detachable pet leash;

[0024] The detachable pet leash's locking mechanism contains a rechargeable battery, a functional circuit board electrically connected to the rechargeable battery, and a power supply unit that charges the rechargeable battery through the functional circuit board.

[0025] Optionally, the functional circuit board includes a wireless communication module for remote communication with a wireless terminal.

[0026] Optionally, the functional circuit board includes at least one of a microphone, a speaker, and a positioning module.

[0027] Optionally, the latch body is a transparent structure, and the functional circuit board is provided with several LED beads.

[0028] On the other hand, a remote pet monitoring system is provided, including any of the aforementioned smart pet leash and a wireless terminal wirelessly connected to the smart pet leash.

[0029] The beneficial effects of this invention are as follows: it provides a detachable pet leash, a smart pet leash, and a remote pet monitoring system, the working process of which is as follows:

[0030] S10: Snap-fit ​​operation. The user inserts the recessed block into the base recess at a slightly tilted angle, aligning the hook with the rear wall slot. Then, the recessed block is placed into the base recess, gradually shifting from an tilted position to a horizontal position during insertion. Simultaneously, the depth of the hook insertion into the rear wall slot gradually increases. The snap-fit ​​is complete when the bottom surface of the recessed block is flush with the bottom of the base recess. At this point, a gap is formed between the front end of the recessed block near the front wall of the base and the rear wall of the base.

[0031] S20: Unlocking Operation. When it is necessary to separate the detachable latch, the user applies an unlocking pull parallel to the opening of the base recess to the front of the detachable latch (e.g., by pulling the unlocking cord connected to the front of the detachable latch). Due to the existence of the gap space, the recessed block gains lateral movement space during the lifting process, allowing the hook to partially disengage laterally from the rear wall slot. As the lifting continues, the hook gradually disengages from the rear wall slot, and finally the hook completely disengages from the rear wall slot, achieving unlocking.

[0032] S30: Anti-misunderstanding lock mechanism.

[0033] (1) When the pet walks in front of the owner, causing the leash to be straightened (equivalent to the owner pulling the detachable buckle backward through the leash), the hook protrudes backward and inserts into the slot on the back wall. Therefore, in this state, regardless of whether the gap is large or small, the more the pet walks forward, the less likely the detachable buckle will be to come off the buckle base, thus avoiding the buckle detachment problem.

[0034] (2) When the owner walks in front of the pet, causing the leash to be straightened (the owner pulls the detachable buckle forward with the leash), if the width of the gap is too large (for example, the width of the gap is greater than the protrusion of the hook), then the entire hook will be pulled forward out of the rear wall slot, and the detachable buckle will be disengaged from the buckle base; therefore, the width of the gap is smaller than the protrusion of the hook.

[0035] In summary, the detachable pet leash, smart pet leash, and remote pet monitoring system provided by this invention achieve reliable fastening and unlocking through a rigid limiting structure, avoiding the use of elastic components. Therefore, it can solve the problem that the elastic buckles used in existing pet leashes are prone to failure due to fatigue and aging. Attached Figure Description

[0058] This invention provides a detachable pet leash, a smart pet leash, and a remote pet monitoring system. It achieves reliable fastening and unlocking through a rigid limiting structure, avoiding the use of elastic components. Therefore, it can solve the problem that the elastic buckles used in existing pet leashes are prone to failure due to fatigue and aging.

[0059] The following detailed description, with reference to the accompanying drawings, explains the structure and function of the detachable pet leash, the smart pet leash, and the remote pet monitoring system.

[0060] Example 1

[0061] The detachable pet leash provided by this invention mainly achieves reliable fastening and unlocking through a rigid limiting structure, avoiding the use of elastic components, thereby solving the problem of traditional plastic buckles failing due to fatigue and aging. The core lies in the ingenious setting of the interval space, which makes unlocking necessary to be completed in a specific direction, while the pulling force in other directions is effectively limited, preventing accidental locking.

[0062] See Figures 1-5 The detachable pet leash 100a provided in this embodiment includes a wearable part 100a1 for animals to wear, a leash 100a2 for human hands to hold, and a rigid buckle 100a3 for connecting the wearable part 100a1 and the leash 100a2.

[0063] Specifically, the rigid fastener 100a3 includes:

[0064] The fastener base 1 has a base groove 101 with an open structure. The base groove 101 has a base front groove wall 1011 and a base rear groove wall 1012 that are arranged opposite to each other. The base rear groove wall 1012 has a rear wall slot 1012a.

[0065] The detachable latch 2 has a recessed insert 201 at its lower part that is inserted into the base groove 101 through the opening of the base groove 101. The recessed insert 201 has a hook portion 2011 protruding toward the rear wall groove 1012a at its lower part near the rear end face of the rear wall groove 1012a.

[0066] in,

[0067] When the detachable latch 2 and the fastener base 1 are fastened together, the hook part 2011 is accommodated in the rear wall slot 1012a, and a gap space 3 is left between the rear slot wall 1012 of the base and the groove insert 201;

[0068] The interval space 3 is used to provide clearance space for the hook part 2011 to completely exit the rear wall slot 1012a to achieve unlocking when the front end of the detachable latch 2 is lifted upward by an unlocking pull parallel to the opening direction of the base groove 101.

[0069] Furthermore, the width of the interval space 3 is smaller than the protrusion of the hook portion 2011, so as to restrict the hook portion 2011 from completely exiting the rear wall slot 1012a when the detachable latch 2 is subjected to a pulling force toward the front groove wall 1011 of the base.

[0070] Specifically, when applied to pet leashes:

[0071] The buckle base 1 of the rigid buckle 100a3 is fixed on the wearing part 100a1 of the pet leash, and the front groove wall 1011 of the base is close to the head of the pet.

[0072] The detachable locking buckle 2 of the rigid fastener 100a3 is fixed to one end of the traction rope 100a2;

[0073] After the pet wears the wearing part 100a1, fasten the detachable lock 2 onto the buckle base 1, and then the pet can be led by the leash 100a2.

[0074] The design of the interval space 3 is one of the core innovations of this invention. The width of the interval space 3 is designed to simultaneously achieve reliable locking and convenient unlocking. Specifically, the width of the interval space 3 is smaller than the protrusion of the hook portion 2011. Therefore, when the detachable latch 2 is subjected to a pulling force toward the front groove wall 1011 of the base (such as the pulling force generated when a pet moves forward), the hook portion 2011 cannot completely exit the rear wall slot 1012a, effectively avoiding accidental locking. On the other hand, when unlocking is required, the user applies an unlocking pulling force parallel to the opening of the base groove 101 (such as a roughly vertically upward pulling force). The front end of the detachable latch 2 lifts upward and moves in an oblique upward manner. The interval space 3 provides the necessary lateral movement and lifting space for the hook portion 2011, allowing the hook portion 2011 to completely exit the rear wall slot 1012a.

[0075] The working process of rigid fastener 100a3 is as follows:

[0076] S10: Snap-fit ​​operation. The user inserts the recessed block 201 into the base recess 101 at a slightly tilted angle, aligning the hook portion 2011 with the rear wall slot 1012a. Then, the recessed block 201 is placed into the base recess 101. During insertion, the recessed block 201 gradually changes from an tilted state to a horizontal state, and simultaneously, the depth of the hook portion 2011 inserted into the rear wall slot 1012a gradually increases. When the bottom surface of the recessed block 201 finally adheres to the bottom of the base recess 101, the snap-fit ​​is complete. At this point, a gap space 3 is formed between the front end face of the recessed block 201 near the front wall 1011 of the base and the rear wall 1012 of the base.

[0077] Optionally, the recessed insert 201 is provided with an insert magnetic 204 inside, and the bottom of the base recess 101 is provided with a base magnetic 102 for magnetically connecting with the insert magnetic 204.

[0078] The base magnetic 102 is located directly below the opening of the base groove 101 and biased towards the side of the rear wall slot 1012a. It is used to apply a magnetic attraction force towards the rear and downward to the insert block magnetic 204 during the fastening process, so that the upper part of the groove insert block 201 near the rear end face of the rear wall slot 1012a is in close contact with the upper edge of the rear wall slot 1012a, so as to maintain the fastening state of the detachable lock 2 and the fastener base 1.

[0079] Because there is a magnetic attraction between the recessed insert 201 and the fastener base 1 towards the rear and downward, the recessed insert 201 is automatically attracted to the horizontal position during the fastening process by the magnetic attraction. Moreover, after the fastening is completed, the upper part of the rear end face is close to the upper edge of the rear wall slot 1012a, thereby ensuring that the entire hook part 2011 is fully inserted into the rear wall slot 1012a, and minimizing the possibility of mis-locking.

[0080] Furthermore, one of the insert magnetic absorbing member 204 and the base magnetic absorbing member 102 is a first magnet, and the other is an iron block or a second magnet with the opposite polarity to the first magnet.

[0081] S20: Unlocking Operation. When it is necessary to separate the detachable latch 2, the user applies an unlocking pull force parallel to the opening of the base groove 101 to the front end of the detachable latch 2 (e.g., by pulling the unlocking pull rope 202 connected to the front of the detachable latch 2). Due to the presence of the gap space 3, the groove insert 201 gains lateral movement space during the lifting process, allowing the hook part 2011 to partially exit laterally from the rear wall slot 1012a. As the lifting continues, the hook part 2011 gradually exits the rear wall slot 1012a, and finally the hook part 2011 completely disengages from the rear wall slot 1012a, thus achieving unlocking.

[0082] S30: Anti-misunderstanding lock mechanism.

[0083] In fact, the width of the interval space 3 needs to be designed.

[0084] (1) When the pet walks in front of the owner, causing the leash 100a2 to be straightened (equivalent to the owner pulling the detachable buckle 2 backward through the leash 100a2), since the hook part 2011 protrudes backward and inserts into the rear wall slot 1012a, in this state, regardless of whether the interval space 3 is large or small, the more the pet walks forward, the less likely the detachable buckle 2 can be separated from the buckle base 1, thereby avoiding the buckle problem;

[0085] (2) When the owner walks in front of the pet, causing the leash 100a2 to be straightened (the owner pulls the detachable lock 2 forward through the leash 100a2), the size design of the gap space 3 reflects the trade-off between "preventing accidental unlocking" and "facilitating unlocking".

[0086] If the width of the interval space 3 is too large (for example, the width of the interval space 3 is greater than the protrusion of the hook part 2011), then the entire hook part 2011 will be pulled forward out of the rear wall slot 1012a, and the detachable lock 2 will disengage from the fastener base 1; therefore, the width of the interval space 3 is smaller than the protrusion of the hook part 2011.

[0087] However, the gap space 3 cannot be too small. If the gap space 3 is too small, when the front end of the detachable latch 2 is pulled upward, there will not be enough space in front of the grooved insert 201 for the grooved insert 201 to be lifted upward. That is, the front end face and the front groove wall 1011 of the base will interfere due to insufficient gap. This will not only prevent unlocking, but also prevent successful locking (the detachable latch 2 will interfere with the front groove wall 1011 of the base during the process of switching from tilt to horizontal, and ultimately cannot be locked).

[0088] Furthermore, the key to unlocking lies in whether the front end of the recessed insert 201 can be successfully lifted to the slot position of the base recess 101. The feasibility of this lifting action is essentially a geometric problem, involving the following parameters:

[0089] (1) Width dimension (A) of the space 3: It determines how much room for movement the front end of the grooved insert 201 can have when the detachable latch 2 is lifted upward.

[0090] (2) The height dimension of the groove insert 201 (H, the height dimension is parallel to the depth direction of the base groove 101): It determines how much activity space the front end of the groove insert 201 needs to be able to be smoothly lifted to the slot position of the base groove 101 when the detachable latch 2 is lifted upward.

[0091] (3) The protrusion dimension (P) of the hook part 2011: This directly determines whether the hook part 2011 can easily disengage when subjected to forward pulling force (i.e., P must be greater than A).

[0092] (4) The height difference between the rear wall slot 1012a and the hook part 2011 (∆H, the height of the rear wall slot 1012a is greater than the height of the hook part 2011, and the height is parallel to the depth direction of the base groove 101): This determines whether the hook part 2011 has sufficient vertical space to move upward during the unlocking process, and does not reflect off the top edge of the rear wall slot 1012a, causing it to jam.

[0093] Because of the existence of the interval space 3, the unlocking pull force does not necessarily have to be completely vertical and upward, providing an allowable unlocking pull force angle deviation. Furthermore, the larger the width of the interval space 3, the smaller the height of the groove insert 201, the smaller the protrusion of the hook part 2011, and the greater the difference in height between the rear wall groove 1012a and the hook part 2011, the greater the allowable unlocking angle deviation, but correspondingly, the higher the risk of mis-locking.

[0094] In this embodiment, to reduce design complexity, the width of the interval space 3 can be determined first based on the protrusion dimension of the hook portion 2011. For example, the width dimension A of the interval space 3 can be set to be greater than 1 / 4 of the protrusion dimension of the hook portion 2011. Then, the height dimension H of the groove insert 201 is designed to be a smaller value, significantly lower than the maximum height of the groove insert 201 allowed by A. Similarly, ∆H is also directly set to a larger value to avoid vertical interference when the hook portion 2011 is raised. At this point, only the protrusion dimension of the hook portion 2011 and the width dimension of the interval space 3 need to be specified. Of course, in some other embodiments, the width dimension of the interval space 3 can also be set to be greater than 1 / 3 or 1 / 2 of the protrusion dimension of the hook portion 2011, etc. The specific value can be weighed and chosen according to design needs, and this invention does not limit this. This can achieve good fastening to avoid accidental unlocking and also have a more suitable unlocking pull angle, reducing the difficulty of unlocking.

[0095] Therefore, the rigid buckle 100a3 provided by the present invention achieves reliable fastening and unlocking through a rigid limiting structure, avoiding the use of elastic components, thus solving the problem that existing elastic buckles for pet leashes are prone to failure due to fatigue and aging.

[0096] In this embodiment, the front groove wall 1011 of the base is an inclined surface, and the width from the front groove wall 1011 to the rear groove wall 1012 of the base gradually decreases from top to bottom, thus forming a space 3 that is narrower at the bottom and wider at the top.

[0097] (1) Enhanced reliability of anti-mislocking ("narrower bottom effect"): When the detachable latch 2 is engaged, the recessed insert 201 is located at the bottom of the base recess 101. At this time, due to the presence of the inclined surface, the gap between the lower part of the front end face of the recessed insert 201 and the front groove wall 1011 of the base is in the smallest "narrow area". When subjected to an unexpected pulling force towards the front groove wall 1011 of the base, the recessed insert 201 contacts the inclined surface almost immediately, and the pulling force is directly transmitted as a normal pressure on the groove wall, rather than being converted into a torque that lifts the front end of the recessed insert 201 upward, thereby greatly suppressing the unfavorable rotation with the hook part 2011 as the fulcrum and effectively preventing accidental disengagement.

[0098] (2) Optimized unlocking action ("wider upper effect"): During intentional unlocking, when the front end of the detachable latch 2 is pulled upward, the front end of the recessed insert 201 is lifted upward. As the lifting height increases, the width of the gap space 3 in front of the recessed insert 201 gradually increases due to the inclined surface design (entering the "wide zone"). The recessed insert 201 will not interfere with or get stuck on the front groove wall 1011 of the base during the lifting process. The inclined surface provides increasingly ample space for rotation, making the unlocking action very smooth and effortless. Once the front end of the recessed insert 201 rotates to a sufficient angle, the latch 2011 can smoothly disengage from the rear wall slot 1012a, completing the unlocking.

[0099] In summary, the inclined surface design of the front groove wall 1011 of the base, in conjunction with the interval space 3, creates an intelligent, non-uniform accommodating environment: the "narrow space" at the bottom suppresses unfavorable rotation to ensure safety; and the "wide space" on the unlocking path guides favorable rotation for easy operation.

[0100] In this embodiment, the detachable latch 2 further includes a latch body 203 disposed above the recessed insert 201. The latch body 203 protrudes rearward to form a rear protrusion 2031 for connecting the leash 100a2. When the pet walks in front of the owner, the leash 100a2 applies a rearward pulling force to the rear protrusion 2031. This pulling force generates a torque that, with the hook portion 2011 as the instantaneous fulcrum, drives the upper part of the rear end face of the recessed insert 201 to press tightly against the periphery of the rear wall slot 1012a. This torque effectively resists rotation in the unlocking direction, ensuring absolute stability of the latch when the pet lunges forward.

[0101] The latch body 203 protrudes forward to form a forward protrusion 2032 for connecting the unlocking pull rope 202. This design places the unlocking operation point in the front, providing a clear ergonomic interface, allowing users to directly and effortlessly apply a vertically upward unlocking force to the front end of the detachable latch 2 by pulling the unlocking pull rope 202, making the operation very convenient.

[0102] In this embodiment, the bottom surface of the hook portion 2011 is an inclined surface that slopes upward away from the interval space 3, and the top surface of the hook portion 2011 is an inclined surface that slopes downward away from the interval space 3. These two inclined surfaces together optimize the movement trajectory of the hook portion 2011 within the rear wall slot 1012a. Specifically, the inclined bottom surface of the hook portion 2011 primarily serves a guiding function during the fastening process, guiding the hook portion 2011 to smoothly slide into the rear wall slot 1012a; while the inclined top surface of the hook portion 2011 primarily serves a clearance function during the unlocking process, providing necessary space for the hook portion 2011 to rotate upward and exit the rear wall slot 1012a, avoiding interference with the upper edge of the rear wall slot 1012a. These two opposing inclined surfaces together ensure the smoothness and reliability of the fastening and unlocking actions.

[0103] In this embodiment, the upper part of the front end face of the recessed insert 201 near the front groove wall 1011 of the base is provided with a protruding boss 2012 protruding towards the front groove wall 1011 of the base, so that the gap between the upper part of the front end face and the front groove wall 1011 of the base is smaller than the gap between the lower part of the front end face and the front groove wall 1011 of the base. This creates a two-stage unlocking mechanism, which greatly improves the smoothness of unlocking and user experience without weakening the anti-mislocking capability. The unlocking action sequence is as follows:

[0104] (1) High-angle start-up phase. When the user applies the unlocking pull force, due to the presence of the front protrusion 2012, the initial contact point between the grooved insert 201 and the front groove wall 1011 of the base is located at the upper protrusion. This design ensures that in the initial stage of unlocking, the grooved insert 201 must start to rotate with a nearly vertical upward pure upward pull force with minimal angular deviation. This high-precision angle requirement is a key safety guarantee to avoid accidental disengagement due to oblique pulling force during daily traction.

[0105] (2) Low-resistance completion stage. Once the front protrusion 2012 is slightly lifted under the pulling force and disengages from the front groove wall 1011 of the base, the unlocking process immediately enters the second stage. At this time, the force contact point of the grooved insert 201 instantly changes from "point contact (protrusion)" to "surface contact (the entire lower front surface)", and because the lower gap is much larger than the upper gap, the front end of the grooved insert 201 instantly gains a huge rotation space. This makes the subsequent unlocking action extremely smooth and effortless, and the user only needs a small pulling force to easily complete the entire lifting and separation action.

[0106] Therefore, the 2012 front-protruding boss structure cleverly combines "highly secure activation conditions" with "low-operational-load completion processes." It ensures that the unlocking procedure is only initiated when a pulling force with a very clear direction and intention is applied; and once initiated, unlocking can be easily completed, achieving a high degree of unity between safety and ease of use.

[0107] In summary, the rigid fastener 100a3 provided in this embodiment has the following advantages:

[0108] ① By using a rigid limiting structure in conjunction with the interval space 3, reliable fastening and unlocking of non-elastic components is achieved, solving the problem of traditional plastic buckles failing due to fatigue and aging.

[0109] ② By designing the width of the interval space 3 to be smaller than the protrusion size of the hook part 2011, the unlocking pull force in a specific direction can be successfully unlocked, while the pull force in other directions is restricted, effectively preventing accidental locking.

[0110] ③ By setting a magnetic attraction element between the grooved insert 201 and the fastener base 1, the magnetic attraction force is used to assist in guiding and maintaining the fastening state, thereby improving the smoothness of the fastening process and the reliability of locking.

[0111] ④ By designing the front groove wall 1011 of the base as an inclined surface, a space 3 that is narrow at the bottom and wide at the top is formed. This can suppress unfavorable rotation at the bottom to prevent accidental unlocking, and provide ample space at the top for unlocking and lifting.

[0112] ⑤ By setting a protruding boss 2012 on the upper part of the front end face of the grooved insert 201, a two-stage unlocking mechanism is created, which not only ensures a high-security starting condition, but also achieves smooth separation with low resistance in the later stage of unlocking.

[0117] In this embodiment, the functional circuit board 100c is electrically connected to the rechargeable battery 100b and is responsible for controlling electronic functions; the power supply unit 100d (such as a charging interface or wireless charging coil) charges the rechargeable battery 100b through the functional circuit board 100c. When charging is required, the user only needs to remove the detachable latch 2 from the buckle base 1, while the buckle base 1 remains on the pet's wearing part 100a1, without needing to disassemble the entire wearing part 100a1. After charging is complete, the detachable latch 2 can be reattached to the buckle base 1, restoring normal use.

[0118] This detachable design enables convenient charging. Since the base 1 remains fixed to the pet, charging only requires removing the detachable buckle 2, avoiding discomfort caused to the pet by frequently putting on and taking off the wearable part 100a1. It also simplifies user operation and enhances practicality and user experience. Simultaneously, electronic functions are integrated into the detachable buckle 2, allowing the buckle to maintain its traditional leash function while adding intelligent expansion capabilities.

[0119] Therefore, the rigid fastener 100a3 provided by the present invention can improve charging convenience on the basis of integrated electronic functions, thereby enhancing the practicality of the product and the user experience.

[0120] Since the specific magnetic snap-fit ​​structure of the buckle base 1 and the pluggable buckle has been fully described in Embodiment 1, this embodiment mainly focuses on the electronic function part.

[0121] In this embodiment, the functional circuit board 100c includes a wireless communication module for remote communication with a wireless terminal. The wireless communication module (such as a Wi-Fi or 4G / 5G module) is integrated with the functional circuit board 100c and can perform bidirectional data communication with a remote wireless terminal (such as a smartphone or tablet) via wireless signals (such as a cellular network or local area network). Users can install a dedicated app on the wireless terminal to send commands or receive data. The wireless communication module is powered by a rechargeable battery 100b, and its operating status is controlled by the functional circuit board 100c.

[0122] The wireless communication module enables the rigid fastener 100a3 to interact remotely with a wireless terminal, achieving intelligent management. For example, users can monitor their pet's status in real time, receive notifications, or send control commands via an app, expanding the fastener's functionality and improving the pet's safety and controllability.

[0123] Optionally, the functional circuit board 100c includes a microphone 100e and / or a speaker 100f. The microphone is used to collect ambient sound and transmit the audio data to a wireless terminal via a wireless communication module; the speaker 100f receives the audio signal sent by the wireless terminal and plays it. When the user activates the function through the APP, the wireless communication module works in conjunction with the microphone 100e to achieve remote monitoring; and works in conjunction with the speaker 100f to achieve remote voice broadcasting.

[0124] With the microphone 100e and / or speaker 100f, users can remotely listen to sounds around their pets (such as to determine if the pet is uneasy) or send voice commands to the pets (such as soothing commands), thereby intervening in a timely manner when the pet is lost or frightened, enhancing human-pet interaction, and improving safety.

[0125] Optionally, the latch body 203 is provided with a sound-permeable mesh 100k to avoid blocking sound transmission, thereby improving call quality.

[0126] In this embodiment, the functional circuit board 100c includes at least one of a GPS positioning module 100g, a Beidou positioning module 100g, and a Bluetooth positioning module 100g. The positioning module 100g acquires location data via satellite or Bluetooth signals and transmits the location information to a wireless terminal APP via a wireless communication module. The APP can process this data to display the pet's real-time location, historical trajectory, or set an electronic fence (safe zone). When the pet exceeds the safe zone, the APP will trigger an alarm (such as a pop-up window or sound alert).

[0127] The 100g positioning module provides accurate location and trajectory tracking, helping users monitor their pet's whereabouts in real time. The electronic fence alarm function provides timely warnings of the risk of loss, greatly reducing the possibility of pets getting lost, especially suitable for complex outdoor environments.

[0128] In this embodiment, the latch body 203 is a transparent structure, and the functional circuit board 100c is equipped with several LED beads 100h. The LED beads are controlled by the functional circuit board 100c, and the user can send commands via a wireless terminal APP to control the on / off mode of the LED beads (such as constant on or flashing). The transparent latch body 203 ensures that light can pass through, providing illumination or signal indication.

[0129] At night or in low-light environments, the constant illumination of LED beads can help users intuitively locate their pets; when searching for a pet, controlling the flashing of LED beads (such as red light) can enhance visual recognition, improving safety and convenience.

[0130] In this embodiment, the functional circuit board 100c is equipped with an electronic switch 100i, and the latch body 203 is equipped with a button structure 100j corresponding to the position of the electronic switch 100i. The button structure 100j and the electronic switch 100i are mechanically linked: when the user presses the button structure 100j, it triggers the electronic switch 100i to move downwards or upwards, thereby changing the circuit's on / off state. The first press turns the device on, and the second press turns it off. The electronic switch 100i controls the overall power supply to the functional circuit board 100c and the rechargeable battery 100b. Through the button structure 100j and the electronic switch 100i, the user can conveniently turn the device on and off, avoiding wasting power during non-use periods (such as indoor rest), extending battery life, and achieving energy saving.

[0131] The power supply unit 100d includes a wired charging interface for plugging and unplugging with a charging plug, and / or a wireless receiving coil for wireless charging with a wireless power supply coil. Correspondingly, the latch body 203 has a charging hole exposing the wired charging interface, and a sealing ring is provided between the wired charging interface and the charging hole for dust and water resistance. The dual charging methods provide flexibility, allowing users to choose between wired or wireless charging depending on the scenario.
